Organic semiconductors have recently been shown to be promising alternatives to their inorganic counterparts because of their low cost, light weight and flexibility. As a result, such compounds are being explored for optoelectronic applications. Organic light-emitting diodes (OLEDs) have gained commercial acceptance due to their potential use in high-resolution displays and solid-state lighting. The intrinsic advantages of OLEDs (tunable color range, ease of manufacturing, flexibility) over their LED counterparts have facilitated consideration for next generation consumer electronics. However, OLEDs have not been fully commercialized due to limited life span, stability, and diminished efficiencies, especially in regard to blue emitters. Thus, in order for these devices to reach their full potential, significant advances need to be made in order to improve the fundamental limitations noted above. For this reason, we have begun to explore the syntheses of alternative compounds as possible blue emitters. In this study, we outline the design, synthesis, and characterization of compounds for deep blue fluorescence by employing electron deficient pyrimidine derivatives and electron rich pyrene moieties. Characterization of these synthesized compounds entails various measurements including thermostability, photostability, UV-vis absorbance and fluorescence, thermogravimetric analysis, differential scanning calorimetry, and cyclic voltammetry.  The results of these studies to date will be outlined in this talk.<br/> <br/>
